IIMPROVEIYIEN'T IN SASHSTOP.

The Schedule referred to in these Lettere Patent and making part of the same.

To all whom 'it may concern:

Be it known that we,'WrLLIAM J. MANKER and ALLEN T. MANKER, both of Indianapolis, in the county of Marion, andSt-ate of Indiana, have invented a new and improved Mode of Supporting Window- Sashes; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, i'orrn ing part of this'speciiication, and in which- Figure 1 is an interior View of a window with our improvement applied thereto;

Figure 2 is a modication of spring-balance shown in iig. 1, but not forming, by itself, our invention; and

Figure 3 is an enlarged View of the cam-lever shown in iig. l..

In the drawings- K A is the frame, B, the sash, and C, the stop of a common window.

The sashes, both upper and lower, are hung by-a cord, in the usual manner, that is wound upon a drum, E, contained in a box, F, which may be made, of castiron, in any convenient or practicable manner, one of which is let into each side of the frame, near the top, for the upper sash, and one on each side, near the meeting rail, for the lower sash. The drum E is iixed upon a shaft, to which the inner end of' the coiled spring G is attached, the outer end of the spring being attached to the box.

In hanging the sashe's, the cord D is wound upon the drum E, so that, in drawing out the cord, to attach it to the sash, the spring will be wound up sufficiently for the tension to connterbaiance their weight, when used in connection with the cam-lever or stop hereinafter referred to.

In this way, also, the same-size sprin g may beadapted to different weight of sash.

In connection with these is used the cam-lever L, which serves to support the sash, or sashes, when two are used, in any desired position.

This cam-lever is pivoted, at n, to the sash, and is` operated by the handle I.

Rubber or other elastic material is inserted, or otherwise fastened to the --end of the lever, at K, which, Whenpressed againstlthe strip C, by the action of' a spiral spring, l?, creates sufficient friotion-to sustain the window at any desired height.

The spring P is coiled in a box, S, which, being secured, or forming part of the plate T, is secured to
